SPIDER is a technique for measurement spectral phase of femtosecond optical pulses. In SPIDER setup, two replicas of the input pulse to be characteri zed are generated with a fixed time delay between them. These two replica pu lses are then upconverted by sum-frequency mixing with a strongly chirped pulse derived from the same original input pulse.

If playback doesn't begin shortly Spider silk is a tough, elastic and lightweight biomaterial, although there is a lack of tools available for non-invasive processing of silk structures. Here we show that nonlinear multiphoton interactions of silk with few-cycle femtosecond pulses allow the processing and heterostructuring of the material in ambient air.

VICTUS® Femtosecond Laser Platform - Full Vision & Versatility With thirty years of experience in the ophthalmic laser surgery field, the 3rd Generation VICTUS ® Femtosecond Laser Platform combines our expertise in surgeon and patient needs with German engineering and intuitive design. Spider silk is a protein fibre spun by spiders.Spiders use their silk to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. Spectral Phase Interferometry for Direct Electric-field Reconstruction (SPIDER) is a specific implementation of spectral shearing interferometry for the complete temporal characterization (or more specifically the spectral phase) of ultrashort optical pulses. Advances in femtosecond methods are crucial to the understanding of ultrafast phenomena in nature.

The SPIDER (Spectral Phase Interferometry for Direct Electric field Reconstruction) system provides precise phase-amplitude measurement of ultrashort laser pulses. The device is widely used for on-line tuning of amplifier systems. The device is used to measure spectral phase, spectral intensity and temporal intensity.

The characterization and control of the phase of broadband femtosecond pulses in nonlinear microscopy are successfully demonstrated with a collinear configuration of spectral shear interferometry for direct electric field reconstruction (SPIDER). A femtosecond-pulse shaper is used as a dispersionless interferometer for the measurement of the spectral phase and to actively compress a broadband Jasper Flex: High Power Femtosecond Fiber Laser. Jasper Flex is our new high-power femtosecond laser for microprocessing. Its compact size makes it even easier to use and to integrate into existing systems.

Beyond compression, the scheme allows precise phase control at the site of the microscopic experiment. We present the SPIDER is a technique for measurement spectral phase of femtosecond optical pulses. In SPIDER setup, two replicas of the input pulse to be characteri zed are generated with a fixed time delay between them. These two replica pu lses are then upconverted by sum-frequency mixing with a strongly chirped pulse derived from the same original input pulse. Spider silk is a biomaterial that has come to intrigue many in recent times.

A thin etalon is used to pick off a portion of the input pulse and split it into two pulses delayed Femtosecond up-conversion is a pump-probe technique that uses nonlinear optics to combine the fluorescence signal and probe signal to create a signal with a new frequency via photon upconversion, which is subsequently detected.
